Abstract:
In Lactococcus lactis excision of Tn916 is limited by the concentration of integrase and is increased by providing more excisionase. However, even with increased excision of Tn916 in L. lactis, no conjugative transfer is detectable. This suggests that L. lactis is deficient in a host factor(s) required for conjugative transposition.
